To solve this problem you must apply the fomrula for calculate the area of a cylinder, which is shown below:
 A=2πrh+2πr^2
 Where r is the radius and h is the height of the cylinder
 You have that r=15.1 inches and h=12.8 inches, then:
 A=2πrh+2r^2
 A=2π(15.1 in)(12.8 in)+2π(15.1 in)^2 
 A=2647 in^2
 The answer is 2647 in^2

1. Which function describes the sequence 2,4,6,8......? *
Lyrx [107]

Answer:

f(1) = 2

f(n) = f(n-1) + 2 where n\geq 2

Step-by-step explanation:

Given

2,4,6,8...

Required

Which function determines the sequence

Represent the terms with n where n is 1,2,3....

Analyzing each term:

f(1) = 2

f(2)= 4 = 2 + 2 = f(1) +2

f(3)= 6 = 4 + 2 = f(2) +2

f(4)= 8 = 6 + 2 = f(3) +2

Notice that each term is an addition of the previous term and 2

In other words:

f(n) = f(n-1) + 2

However, the function is only effective for values of n greater than or equal to 2

So: n\geq 2
